A light receiving device includes a microlens 21 located in each of regions corresponding to pixels, the microlens being disposed on a rear surface of an InP substrate 1. The microlens is formed by using a resin material having a range of a transmittance of light in the wavelength region between 0.7 and 3 μm of 25% or less, the transmittance being 70% or more.

To avoid change in plating performance, even where operation of the plating equipment is interrupted, the properties of the plating solution need to be preserved. For plating equipment having an insoluble anode, add a reservoir (7) for storing a replacement solution to the tank (4) having a metal ion supply source (copper ball (5)) and, upon termination of the plating operation, the entire plating solution is discharged from the tank (4) containing the metal ion supply source, while the solution for replacement is transferred from the reservoir (7) to the empty tank having a metal ion supply source, and immediately prior to the resumption of the plating operation transfer the solution for replacement back to the reservoir (7) and return the plating solution to the tank (4) containing the metal ion supply source.

Images formed by a liquid are transferred onto both sides of a sheet-like recording medium without the liquid running on or penetrating into the recording medium. A layer of absorbing powder is formed on an intermediate transfer member. The liquid is applied to the powder layer formed on the intermediate transfer member so as to form a first visible image. The first visible image is transferred onto the front side of the recording medium. Thereafter, another layer of the absorbing powder is formed on the intermediate transfer member, and the liquid is applied to the powder layer so as to form a second visible image. The second visible image is transferred onto the back side of the recording medium.

A device outputting a plurality of paths to a terminal after rearranging the plurality of paths when the paths are arranged in an order of free choice on a side of a communication line, the device having a counter which receives a path number of a path in response to first data about the path, and increments a count, starting from the path number, in response to additional data arriving and a storage unit, shared by the plurality of paths, which stores real data of the path at positions indicated by the count, and where the real data stored in the storage unit is output to the terminal.
摘要:
In a method of and an apparatus for regenerating an image support from a used image-bearing support which bears thereon hydrophobic images formed of thermofusible or heat-softening ink, a plurality of image releasing members are used for removing the hydrophobic images from the used image-bearing support. Specifically, at least one of the image releasing members has a first portion which is able to adhere to the hydrophobic images and a second portion which is unable to adhere to the hydrophobic images, and the image releasing members are arranged in series in order of size of the first portion from small to large along a feeding direction of the used image support. Accordingly, the image releasing members are allowed to adhere to the hydrophobic images in order of size of the first portion from small to large so that the hydrophobic images are removed from the used image support effectively. It is preferable that the image releasing member finally allowed to adhere to the hydrophobic images is a solid image releasing member.

A semiconductor package device is disclosed. In one embodiment, attached by its active face to a lead-on-chip leadframe having leadfingers is an integrated circuit. The integrated circuit has a polyimide coating on its backside. An encapsulating material surrounds the integrated circuit and the lead-on-chip leadframe so that the leadfingers are exposed. The polyimide coating on the backside of the integrated circuit helps to reduce package cracking arising from mounting the device to a printed circuit board by relflow solder.

In a method of recording/reproducing information associated with an apparatus and recording medium, the medium has an alternate formation including tracks of first regions wherein at least an optical record of preformatted pits at a constant time interval is recorded and second regions in which information is recorded so that optical retrieval can be achieved. A clock signal is generated based on the readout signal of the preformatted pits to record an information signal in the second regions, and the clock signal is retarded and used to read out data pits that are the record of the information in the second regions.
摘要:
An image removing method including bringing an outermost layer of a removing member into contact with an image fixed on an image support without applying a liquid to the image while heating the image and the outermost layer; and separating the removing member from the image support to remove the image from the image support, wherein the removing member includes a substrate and the outermost layer which is located overlying the substrate and which includes a thermoplastic resin, and wherein the image includes a removing agent which can decrease adhesion force of the image to the image support when heated.
